q_slots - C++ Qt Signals and Slots rama 888 slot

Since display() is part of the class's interface with the rest of the program, the slot is public. ... The public API of Qt-based libraries should use the keywords Q_SIGNALS and Q_SLOTS instead of signals and slots.

The public API of Qt-based libraries should use the keywords Q_SIGNALS and Q_SLOTS instead of signals and slots. Otherwise it is hard to use such a library in a project that defines QT_NO_KEYWORDS.

PS: The slot and the signal have been properly declared in header files using the Q_SIGNALS and Q_SLOTS keywords, with the correct argument (aStruct).
